"He had a much larger role in the original novel, he was the engineer of this breakthrough in de-extinction. He spent two decades living in Hammond’s shadow, under appreciated. We think there’s more to his story."

Asked about whether he would be bringing back other characters, Trevorrow says:

"I know a lot of fans want to see the original characters back. They're iconic. But I respect those actors too much to shoehorn them into this story for my own sentimental reasons. Jurassic Park isn't about the bad luck of three people who keep getting thrown into the same situation. The only reason they'd go back to that island is if the screenwriters contrived a reason for them to go."

Chris Pratt and Bryce Dallas Howard are the lead stars of "Jurassic World" and Trevorrow spoke a bit about Pratt's character:

"He's a classic hero in a very modern context. He's the guy who will get you through the jungle alive – but like Malcolm, Grant and Sattler, he's an expert in a scientific field that's connected to our story. The character allows us to explore some new ideas about our relationship with these animals, without losing the humor and sense of adventure. He's a great contrast for Bryce Dallas Howard's character, who starts off very corporate, very controlled. Until the running and screaming starts. Then they need each other."
